I want to place my printer in a narrow cabinet 50 cm wide. The filament spools will be in the dryer at the bottom. And the feeders will be moved to the mount behind the printer. Nothing new, I didn’t come up with this. But there is one problem with this layout. I plan to use RFID tags. But the sid…

[U1 ACR122U Mod] [U1 ACR122U Mod] That would be ideal! Maybe Paxx12 is planning to do something like that? Does anyone know anything about it?

Here is something to read: [image] How to extend RFID coils? U1 Toolchanger Hi, in case anyone missed it, there are news concerning rfid readers. With paxx12’s latest release of the custom firmware there is support for external rfid readers: and a github re…

So you don’t want to use the paxx12 either? It (reportedly) includes facility for external RFID (and widens the scope to OpenSpool).

I found this information. But to me, it’s like some kind of alien language. I’ll wait for a ready-made solution. Very interesting - and here’s the good news: support for external RFID readers has already been officially merged into the main paxx12 firmware, without the need for a fork. But there i…

Maybe I didn’t explain something clearly. I have paxx12 installed, but I don’t know how to use it on my own.
